This card definitely has potential, but I don't think it reaches it knowing what we know so far.  Serpent Egg give a better stat spread on hatching and there arent actually that many cards that will hit this from discard since many of the run effects target the most expensive card, which will almost never be this.  Warlock also doesn't currently have much in the way of making use of more bodies since Grim Rally rotated, but I remain optimistic in the Warlock reveals to come.  

Super duper easy to activate in both classes for little to no investment.  Warlock likes hero powering anyway and priest has more than enough tools outside of their hero power to use this.  It also pushes both tempo and control in both classes, which I am a huge fan of.

I think this is a pretty decent card and is not dissimilar to Restless Mummy, but with more rogue flair to it.  Feels weird seeing an effect this tame on a legendary though after Rattlegore was revealed.

I like this card.  Although I am still salty about DH's running all of AoO meta, I like seeing DH pushed towards a more control-y direction.  It even supports the swarm DH that never took off.

As it currently stands I don't see this card being too relevant in standard.  Weapons don't get that much attack right now in either class and while not much is needed for a good play, the investment and unreliability make it too clunky to run over more consistent cards.

Shadow Bolt for midrange, small AoE for aggressive lists, this card seems crazy good.

Seems really good Highlander Mage and Control Shaman or Priest.  Priest has access to very cheap removal and Shaman can get discounts on their damage removal spells.  Also adore the flavor of him using the academies signature mechanic while also referring to his necromancy.

Don't think this will see much play since decks that generally want Rush already seem to have ample ways to get it.  Maybe its sleeper OP, but I can't currently conceive of any ways that this is especially useful.

Seems really good in any control-y decks since it can helpfully answer buffed or large threats.

Good grief, this with Spell Druid is gonna be nuts.  Mountseller pop-offs are gonna even easier and nuttier to pull of.

This is really spooky with Kael still around, but we'll see if it's spooky enough to beat the consistency of general spell spamming.

Does Frazzled Freshman count for Silverback Family Reunion since they're a 1 mana 1/4, or is that spot reserved for neutral Taunt minions with similar statlines?

There are some pretty good 1-drops, including the new Frazzled Freshman.  This card certainly has potential in aggressive decks and maybe in Pure/Libram just to have early plays more consistently.

Given that Spell Druid is a solid deck right now and only seems to be getting more support, I think this card will definitely see play.  An effective 0-mana discover effect is very good, especially when you consider this next to Raven Idol, which also saw good amounts of play almost exclusively for its discover spell effect.

Excellent, more fodder for my Dragon Casino Mage.  I think its probably a bit slow though.  Cobalt gave targeted spell addition, random spells might be too unreliable or niche for this to see regular play.

Super strong and fantastic for burgle Rogue.  Super cheap generators on a body are almost always played, so I have high hopes for this card.

Now that's a spicy little effect.  Seems good for midrange and control Shaman decks.

A cure little spell-tech card, but idk if it will see play.  The number of decks it counters is questionable and the effect isn't nearly as debilitating as Loatheb.  

We'll have to see if there are any cheap buff spells, but I like that we're getting closer and closer to a Zoo Priest being a thing.

Very difficult to assess since the effect cannot be relied upon, but 5 stars for creativity and uniqueness.
